The solar PV sector in Croatia is comprised almost entirely of small-scale rooftop systems, owing to a lack of industry/investor interest in the development of larger solar projects (as opposed to wind energy projects), according to recent reports. Based on the most recent figures released by the country’s energy market manager (HROTE), installed solar PV capacity there hit 30.3 MW
A recent 18-month-long research partnership between Siemens Energy Management Division and Duke Energy, created with the intent of reducing EV charging technology costs, has borne fruit, according to a new press release. The two companies recently demonstrated the results of the collaboration at the Duke Energy Envision Center in Erlanger, Kentucky — utilizing a Ford Fusion Energi plug-in hybrid electric
South Korean PV module manufacturer SolarPark Korea has supplied modules to the first floating solar PV power plant in the country, the prototype Sunflower Solar Power Plant, which uses a tracking and rotating system. According to SolarPark Korea, the tracking system rotates the PV plant so that the modules face the most sun throughout the day. As the facility floats
Murata has announced the DRQ series of single output digitally controlled 500W and 600W dc-dc converters from Murata Power Solutions. Incorporating a 32-bit ARM7 Processor, the 600W DRQ-12/50-L48 & 500W DRQ-12/42-D48 models are the second product families offered by Murata Power Solutions to include a PMBus™ compatible digital interface. The DRQ family is packaged in the industry standard quarter-brick format
GE’s Digital Energy business announced its Encompass™ and RevenueSense™ 600-volt current transformers. Both products enable a utility to maximize billing revenue by ensuring more precise meter readings. Due to the range of applications that both products can cover, a utility also can reduce its inventory by up to nearly 90 percent when using these products.

Diodes Incorporated announced a family of pwm controllers designed to improve operating efficiency and eliminate no-load losses. The AP3125 current-mode devices have been optimized for use in offline ac-dc converters in portable products, consumer electronics and domestic appliances. The improvement in performance is a result of the devices’ three operating modes. In normal mode, switching frequency is either 65kHz or
Allegro MicroSystems, LLC announces a new three-phase, sensorless, brushless dc (BLDC) motor controller for use with external complementary P-channel and N-channel power MOSFETs. Reliable sensorless startup and run commutation can quickly be customized for individual motors and loads with adjustment of a few simple default parameters saving considerable design time. The A4963 fits a wide range of applications since the
The Arduino Robot is the first official Arduino on wheels. The robot has two processors, one on each of its two boards. The Motor Board controls the motors, and the Control Board reads sensors and decides how to operate. Each of the boards is a full Arduino board programmable using the Arduino IDE. Both Motor and Control boards are microcontroller
Orion Fans, Inc. has expanded its high airflow fan tray offering to include a front exhaust unit available with up to six-fan positions. Designed for narrow depth cabinets found in security, audio and A/V applications, the OA406 Series ac fan tray combines small size – only 1U high – with reliable performance and high airflows of up to 160 CFM.
Researchers over at Lawrence Berkeley National Laboratory have made a new lithium-ion battery discovery that could prove a little disconcerting to a lot of folks in the energy storage field. The finding comes out of a first-of-its-kind analysis using X-ray absorption spectroscopy, and apparently it contradicts “numerous” studies aimed at improving the efficiency of lithium-ion batteries. The good news is,
